An example of an AI chatbot conversation about converting data types to boolean in Python.
How do I convert different data types to boolean in Python?
In Python, you can use the bool() function to convert various data types to boolean. For example, bool(0) returns False, while bool(1) returns True.
What about empty strings or lists?
An empty string '' and an empty list [] both evaluate to False. Any non-empty string or list evaluates to True.
Can you give me examples of other types?
Sure! For instance, bool(None) is False, while bool('Hello') is True. Similarly, bool([1, 2, 3]) is True.
Is there a way to check if a variable is already a boolean?
Yes! You can use the isinstance() function. For example, isinstance(var, bool) will return True if var is a boolean.
